Purpose: The implant-retained obturator prosthesis is the only way to restore the maxillary defects and edentulous jaw.But there is a huge risk for patients who received the radiotherapy in this plan.This risk refers to the harmful bone transplantation,as well as the implant failure.The reason is that radiation not only can kill cancer cells but also has bad influence on bone tissue.To study the radiation damage,it is considered that the model in vitro is better than the model in vivo.The cultured osteoblasts were irradiated with X-ray to establish the irradiated model in this study.The effects of radiation of different doses on the osteoblasts were observed,in order to illustrate the damage of the osteoblasts with radiation of different doses,to provide laboratory evidence for restoration of the implant-retained obturator prosthesis for patients who received the radiotherapy.
